(e.g. transferring them from the hold of a ship), comprises an elongated passageway (40) (Fig. 3, not shown) from which the fish are transferred by an airstream, a chamber 18 in which they are separated from the airstream and are fed along a surface 60 at an acute angle to the horizontal into a liquid bath 12, from which they are subsequently removed. The chamber 18 comprises a cyclone chamber, air being drawn out by a blower (44). A pressure jet of liquid at 78 tends to separate lumps of ice from the fish. A conveyer 86 tends to draw floating fish below the surface. The fish are removed from the bath 12 by an endless conveyer 98. Ice drops through spaced bars (62) (Fig. 1A, not shown) forming the surface 60, and is conveyed away at 68. A water jet 84 assists the latter process. In a modification (Fig. 5), the conveyer 98 is dispensed with, the fish being swept up on to a flume 132. The water loss from the latter is restricted by a pivoted flap 134 which is pushed up by the passing fish. In a further modification (Fig. 5A, not shown), the conveyer 86 is dispensed with, and the suction outlet (28a) is taken from the space above the bath 12, instead of from the chamber 18. In another arrangement of suction outlet (Fig. 9, not shown), the suction blower is connected to a perforated annular housing in the chamber wall above the bath 12. The conveyer 98 may be replaced by a screw conveyer (Fig. 7, not shown).

Abstract: 1413307 Lubricating extrusion dies PONTA-MOUSSON SA 10 Nov 1972 [29 Nov 1971] 51973/72 Heading B5A An extrusion die surface defining at least a portion of an extrusion passage of a cross-section decreasing in the extrusion direction comprises a porous surface through which a pressurized gas, e.g. air, is admitted to provide a lubricating cushion between the surface and the material. The extruder may be a screw, piston or rotary plate extruder, and the material extruded may comprise thermoplastics, rubber, or a paste which is alimentary ceramic or asbestos cement. The porous surface may be sintered metal, porcelain, or china. A mandrel 2, between which and the die 1 relative rotation may be effected, e.g. by rotation of the mandrel, may be omitted for the extrusion of a solid section, but as shown, defines a tubular flow passage for material 3 between the polished surfaces of porous sintered metal elements 14, 27 of the mandrel 2 and 21, 30 of the die body 1, providing lubricating air cushions 40, 41 in a die region 4, and 42, 43 in a die region 5 in which the material passes to a solidified state. The extruded tube may comprise a blow moulding parison. The pressurized gas, which may be heated or cooled, and may effect a chemical function, is supplied to the porous members 14, 21, 27 and 30, via inlets 32, 33, 34 and 35 to chambers 16, 23, 28 and 31, with pressure regulating vents for the lubricating air cushions 40 41 being provided at 36, 37. The gas pressure of the air cushions 40, 41 decreases at a constant rate in the downstream direction, a condition facilitated by a hyperbolic configuration of the passage defining surfaces of the porous members 14, 21 between boundaries 11, 12, the passage being of constant section downstream of the boundary 12. To prevent adhesion of material to the die passage walls, the flow of gas is commenced prior to, and continued after the termination of extrusion.

Abstract: 1307959 Television INTERNATIONAL STANDARD ELECTRIC CORP 11 Nov 1971 [17 Nov 1970] 52378/71 Addition to 1307566 Heading H4F In a decoder for a PAL type chrominance signal 1, circuits 25 and 3-10 separately amplitude and phase demodulate the signal 1, the phase representative signal 18 (U#) is converted directly and after a one line delay 11 by respective halves of a phase coder 13 to pairs of signals 14, 15 and 17, 16 derived from triangular functions approximating the functions sin U# and cos U#, Figs. 2a and 2b (not shown), and after averaging the undelayed and delayed signals at 19, 20 and conversion to the sinusoidal or cosinusoidal function at 21, 22, they are fed together with the output of demodulator 25 to mixers 23, 24 to provide colour difference video signals 26, 27. It is said that in this way saturation errors resulting from the normal PAL averaging process are avoided, although some error in the average phase angle (hue) may arise near to 0 and 180 degrees or 90 and 270 degrees for the cosine and sine functions, respectively. As shown, in the phase demodulator, the signal 1 is limited, 4, and activates a Schmitt trigger 6. The output pulses are differentiated, 7, and applied, together with differentiated pulses similarly derived from a reference subcarrier frequency input 2 to a bi-stable 8 to produce a pulse width modulated phase representative signal. A PAL switch 9 alternately transmits positive and negative versions of this signal to a filter 10 providing the D.C. signal U#. A circuit suitable for converting the signal 18 to signals 14, 15 is described with respect to Fig. 4 (not shown). In variants of the embodiment shown, (a) the shaping circuits 21, 22 may occur before the respective adders 19, 20, or (b) the signal U# may be obtained by synchronously demodulating the output oflimiter 4 and passing the demodulated signal through a PAL switch.

Abstract: 1407196 Changing signal pitch BRITISH BROADCASTING CORP 3 Oct 1972 [16 Nov 1971] 53225/71 Heading H4R In apparatus for varying the pitch of a signal the signal is sampled, the samples fed into a store at a first rate and read out at a second rate, differing from the first with either the writing or reading process periodically caused to jump a predetermined number of stored samples. As described an audio signal is fed through an A to D converter 22 into a store 24 with the writing position in the store controlled by an address generator 32 and address switch 36. The signals are read out of the store under the control of read address generator 34 and address switch 36 and fed out via the D to A converter 40. The write address generator 32 and read address generator 34 are counters controlled, via the control logic 26, by the write clock signal 28 and read clock signal 30 and the counts of the generators 32 and 34 are continuously compared by jump logic circuit 38. When the counts in the two counters approach coincidence, which would entail reading a store as it was being written, the jump logic causes the read generator 34 to jump a number of storage position, either forwards, if the read out is slower than the write in, causing the read out to miss a portion of the signal, or backwards, if the read out is faster than the write in, causing the read out to repeat a portion of the input signal. In an alternative form the store can be recirculating a shift register, of digital or analogue form, with either a fixed input and a moving output tap or a fixed output and a moving input tap. Interpolations can be introduced to remove discontinuities during the jumps.
